SAMUEL BERGS'IEIN', OF MIDDLETOWN, OHIO, ASSIGNOB, TO THE INTERSTATEFOLD- ING BOX COMPANY, OF MIDDLETOWN, OHIO.

PAPER-BOX-MAKING MACHINE AND THE LIKE.

Application filed November 18, 19st. Serial No. 750,646.

To all whom, it may concern:

Be it known that I, SAMUEL Bnncsrmx, a citizen of the United States,residing in Middletown, in the county of Butler and State of Ohio, haveinvented certain new and useful Improvements in Paper-Box- MakingMachines and the like, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to improvements in paper box making machines,having particular reference to the type of machine set forth in mycopending application for patent, Serial No. 722,330, filed June 25,1924.

The main object attained in the present invention consists in a machineadapted to produce a complete box in a single sequence of operations asdistinguished from the earlier invention above referred to in which adouble sequence of operations is required to complete a box.

The advantages of the improved machine consist in the saving of time, orgreatly increased outputof the machine, and the lower cost of productionwhich is thus made possible.

The underlying purpose of the new type of machines, in the present andalso in the preceding invention referred to, is to pro vide a box makingmachine which can be furnished at low cost to users of paper boxes inrelatively small quantities, or in any quantities, which will enablethem to make their own boxes asneeded, thus making it unnecessary tocarry a large stock of boxes in advance of their requirements as is thecase under the present practice.

Under the new practice which my improved machine makes possible, thecustomer is furnished one or more of the box making machines, accordingto his requirements, and he carries a stock of boxblanks ready forforn'iing on the machine. Thus the minimum of storage space for thestock is re quired, and the boxes can be made up as needed. The newpractice also overcomes the tendency to delays under the old practice infilling orders by manufacturers, and enables substantial savings to bemade in cost on small orders, the relatively higher cost of productionby box manufacturers being due to overhead costs and setting-up time onsmall quantity orders.

The new type of machines marks a radical departure from the presentpractice of box boxes.

making, the invention in a broad sense com prising both the apparatusand the process associated therewith for producing the To the end thatthe machines must be adaptable to be operated by such help as may beavailable to the user, the same are simply constructed and arranged forsafe and convenient operation with relatively high output.

To meet the general requirements of the trade, the improved machines arealso adaptable for making boxes of variable shapes and sizes, certainfeatures of the mechanism being made interchangeable one unit withanother to readily adapt the machines to all ordinary variations in sizeand style of the product.

An object attained in the series of inventions set forth in the severalapplications for patents herein referred to and including an applicationfor patent on the new process of manufacturing involved in the practiceof the invention, to be filed in a separate application, is asubstantial improvement of the boxes produced thereon, the betterquality of constructionhaving reference more especially to the improvedconstruction of the glued joints which is a determining condition ofquality of paper box products.

The. means and method of production comprised in the invention whichresult in the realization of these objectives are fully described in thefollowing detailed specification and are defined in principle and byspecific embodiment of coordinated elements in 4.

the appended claims; in the accompanying drawings, the invention isillustrated in an improved construction, it being understood that thedrawings serve to illustrate the invention in one form only, and that itis contemplated in the commercial practice of the invention to make anysuitable modifications of the various coordinated units of the mechanismand in the detail parts as may best serve the functions of the machinesunder the variable conditions of use.

As far as I am aware, my invention is broadly new in the art to which itpertains-the same, considered as a further development of the inventionssubject matter comprised in the series of inventions herein referred to,being of basis character and therefore capable of broad comprehensivetreatment in the definition and scope of the claims In the drawings:

Fig. 5 is a sectional view of the forming blocks and ejector mechanism.

Fig. 6 is a plan view of the work table showing the folding mechanism.

Fig. 7 is a side elevation showing the forming blocks folded andejection mechanism.

The improved machine as here shown com prises a vertical, hollow column1, provided with a base 2, a work-head rotatable in a horizontal planeon column 1 and consisting of four radially extended arms 3 arranged atright angles one relative to another, each of the arms 3 being providedwith a box forming block 4. Associated with the workhead and adapted tocoact with the forming blocks -'.l are a duplex gluing mechanism 56 anda duplex joint-forming mechanism 78 and coordinated mechanisms whichwill presently be described in the more detailed specification.Operation of the several units of the machine is effected by means of apower head comprising a motor 9, reduction and transmission gearing 10,11, 12, 13, ll and constituting a geared transmission from the motor 9to the main drive shaft 16, a belt and balance wheel 17 being interposedbetween gears 11 and 12, the same being adapted to have a power belt.applied thereto for operating the machine independently of the motor 9.Gear 15 i nounted free on drive shaft 16, its operative relationtherewith being controlled by means of a spring tensioned clutchmechanism 18 which in turn is controlled by a trip pin 10 connected by arod 20 to a treddle 21 in base 2 of the machine, the clutch mechanismbeing of well known construction and commonly known as a tight-and-loosepulley connection.

Rotatable movement is transmitted from shaft 16 to the work tablethrough bevel gears 2223, shaft 24, bevel gears 2526, shaft 27, pin gear28, Geneva gear 29, spur gears 30, 82, 33 and bevel gears 34-35, gear 35being secured to the work table. As here shown, the gearing is timed tocause a quarter-turn of the work table upon each full rotation of thepin gear 28 which advances the Geneva gear 29 a quarter-turn upon achdriving engagement therewith, the entire gear train being retained atrest be tween operations of the Geneva gear by the interlockingrelation. between gears 28 29 in the manner well known in Geneva gears.

The box forming blocks 4- are mounted on the radial extensions 8, whichmay appropriately be termed the work-table anvils to have limitedvertical movement relative thereto, each block being formed of twopieces, an inverted U-shaped inner member 4; which is connected directto the anvil by means of pins 36 set in the opposite sides of the anviland extended outward into vertically extended slots 37 in the oppositeside walls of part l. The relation of the parts are such that member 1has limited vertical movement, compression springs 38 being interposedbetween the anvil and the intermcdiate wall of part 4, there being aspring inwardly adjacent each corner thereof, to support the formingblock normally in raised position relative to the anvil. The other partsof the forming block consist of the integral part l which are secured topart l in any suitable manner, as by screws. Parts 4: of variable sizesare adapted to be used interchangeably on parts 1 thus to adapt themachine for making boxes of different sizes.

The forming blocks are further provided with retaining clips 39 arrangedadjacent ioth ends of the block on opposite sides thereof, which serveto hold the box blanks E in position on the blocks during the gluing andjoint forming operations. Each forming block is also provided withejector, or kick-oil mechanism for removing the linished box therefrom.This mechanism consists of a lever -10 pivoted as at 41-1 on each ofparts 4: and provided at its lower free end with a roller or camfollower -12 disposed in the horizontal plane of an outwardly extendedcam d3 secured to column 1 of the machine, the coacting between theparts resulting in av reciprocal movement being imparted to lever 0 uponeach full rotation ol the work-table. A link it. is connected to lever-10, internicdiate roller -1 and its pivot center, and to a rocker arm.3 secured to a transversely extended shaft l6 supported on part 4;. Adownwardly extended kicker arm all is secured to shaft 4.6 and is thusadapted to be reciprecated outwardly upon each actuation of lever 10. Anupwardly extended kicker arm 48 is secured to a rocker shaft if)supported in the lower walls of part l and is operatively connected witharm l? by means of a roller 50 provided on arm 47 intermediate its ends.It will be ob served that there are two of the arms 48 for each ejectormechanism and that arm .4 is interposed therebetween, arms 4;? and 48being normally pressed inwardly and held in vertical. relation relativeto blocks 4 by a spring coiled on shaft as) which acts also to returnthe arms to normal position after each actuation thereof, the outwardmove ment of the arms being eli ective to remove a box from the formingblock as will be more till fully explained in connection with thedetailed operation of the machine.

As best shown in the plan view of the work-table in Fig. 6, the formingblocks are moved successively into positions A, B, C and D, thesuccessive steps of forming a box beginning in position A where theattendant of the machine places the box blanks on the forming blocks.

As illustrated in Fig. 1, the work head has four work supporting unitsof identical construction which, when the machine is at rest, occupypositions A, B, C and D respectively, the direction of operation beingcounter-clockwise as indicated by the arrow. In this position opposite,outwardly extended guides 52 are provided to position the box for heighton the box supporting block 4i so that the folds for forming the jointswill be made uniform on all the boxes. To this end, arms 52 are formedconcave, V- shaped as here shown, on their under side to receive theopen, upward extended flaps a of the end of the box and to retain thesame in vertical position until the first step of folding has been made.Arms are supported on a bar 53 which is slotted as at 54 to permit ofvarying the spacing of the arms relative to each other to suit the widthof the box for which the adjustment is made, bar 53 being in turnsupported by a block 55 adjustable vertically on a rod 56 secured in aplate 57 fixed to the head support of the machine, whereby to set thearms 52 accord ing to the height of the end flaps a of the box. v

An arm 58 is pivoted on rod 56 at its base and in its idle position isdrawn in clockwise direction against a stop 59 by a spring (30, the armhaving secured therein a rearwardly' extended, curved rod 61, which inturn has .a finger 62 and curved rod 63 Secured thereto, the rod 63being adjustable on rod 61 longitudinally thereof. This mechanism servesto effect the first told of the box, a lug 6% extended upwardly fromeach end of the anvils 3 acting upon rotation Of the work head to engagethe finger 62 and thus to rock arm 58 on its pivot center and to movearm (33 forward, in advance of the n'i-ovement ot' the work head, intoengagement with the adjacent end flap act the box at right angles overthe edge of the forming block 4, spring (50 acting to retract arm 58 aslugs 6 L pass out of engagement with finger 62.

The opposite end flap a, upon rotation of the work head, is moved out ofengagement with the other arm 52 and upon further advancement of thework head is brought into engagement with a circumferentially extendedtubular rod 65 supported outwardly of the machine on brackets 66-67 in aplane and in a manner to effect 'a corresponding fold of the oppositeflap a, both flaps 'a- 'beingthen retained in folded relation as theunit sup porting the box moves to position 13. Brackets t3667 areslotted as at 68G9 and tubular rod is arranged telescopically with asecond rod 70 to permit of adjusting the rods radially relative to thework head to suit variations in the size of boxes.

The outstanding improvement in the machine of the present invention overthe machine ot the preceding application for patent herein referred to,consists in the duplex arrangement of the work head mechanisms whichadapts the machine for forming both ends of the box simultaneously andthus to double the production capacity of the machine. To this end,duplicate mechanisms of parts to 70 inclusive are arranged in a lowerplane of the machine and act on the opposite end of the box to effectiolds thereon substantially in the same manner in the first instancedescribed, the du plicate parts being numbered 52 and 70 inclusive. Theaction on the oppo site ends or the box is simultaneous, the

arrangement and operation of the folding mechanisms in the upper andlower planes of operation being substantially the same except that theoperations are in inverse order, that is to say, the upper end of thebox is folded downward and the lower end is folded upward.

The adhesive for the joints is applied to the folded ends of the box inposition B, the adhesive mechanism comprising upper and lower unitscoacting one with the other to apply the adhesive to both sides of thebox simultaneously. The upper unit of the mechanism consists of anadhesive container 71 suspended on a bar 72 which is supported in openbearing slots of spaced arms Tlformed integrally one. with the other andmounted on the head casting of the machine to have vertical reciprocalaction thereon, operable movement being imparted thereto by means or apin and groove connection 75-76 with the main drive shaft 16, thedetails of the arrangement being of well known construction. Thecontainer 71 is provided with a plurality of spring tensioned valvestops 77 coacting with ports in the bottom oi? the container, the endsof the valve stops extending through the ports and being adapted uponreciprocation of the container to be brought into contact with thefolded upper ends of the box supported on the forming block. It will beunderstood that the valve stops act to close the ports when thecontainer is in raised position, and on the down stroke of themechanism, when.

their projecting ends come. in contact with the end of the box on theforming block, and the same are pressed upward to open the ports andthus cause a regulated portion of adhesive to gravitate to the end ofthe stops, the same act to affect a depositof adhesive Cit from eachstop on the folded ends of the box blanks.

The lower unit of the adhesive applying mechanism consists of acontainer 78 supported on a plate 79, secured to column 1, by means ofset screws 80 operable in slots 81 in plate 79, the arrangementproviding for vertical adjustment of the container as required to suitthe size of the boxes. Coacting with container 78 is an adhesivedepositing mechanism comprising an angularshaped member 82 secured to avertically slidable member 83 by means of a set screw 84 operable in aslot 85 which adapts part 82 to be adjusted vertically on part 83 toretain in the same in normal relation with container 78. Part 83 issupported on part 79 by means of bearing blocks 86, and is adapted to bereciprocated vertically by a pitman 87 connected to a pitman wheelsecured to pin gear 28. The lower portion of member 82 extends over theadhesive container, which is open at the top, and has arranged thereon aSeries of springtensioned pins 89 which are adapted to be submerged,upon the down ward vertical reciprocation of part 82, in the liquidadhesive in container 78, and on the upward movement to be broughtyieldingly in contact with the folded lower end of the box on thesupporting block 4 and thus to effect a deposit of adhesive thereon fromeach of the pins 89, the movement being timed to be substantiallysimultaneous with the deposit of adhesive on the opposite end i of thebox from container 71.

Position C of the work table, as here shown, is an idle position whichprovides a short pause in the sequence of operations to permit theadhesive, applied to the parts of the box to be joined together, to cooland set to a desired extent before the joints are formed.

As the box supporting units move to position D, the coacting part b ofthe ends of the box are engaged by extended arms 90 and 90 respectivelyof the mechanisms in the upper and lower planes of operation, and arefolded over the previously folded parts a as the unit is moved toposition 1) where the joints are formed under opposite pressure heads 7and 8.

Pressure head 7 is reciprocally operable on the power head casting 2being connected to main drive shaft 16 as at 75 in a manner similar tothe connection 75 for actuating the adhesive container 71. The lowerpressure head 8 is supported on a screw 91 adjustable vertically in abearing extended outward from column 1. Coacting with screw 91 onopposite sides of bearing 92 are hand adjusting wheels 98 and 94 bymeans of which the screw and with it pressure head 8 can be raised andlowered and retained in adjusted position. By this arrangement the spacebetween pressure heads 7 and 8 can be accurately regulated according tothe height of the forming blocks 4, or the length of the boxes for whichthe machine is set up. It will be understood from the illustrations ofthe drawings that the upper end of the forming blocks is always in thesame horizontal plane regardless of the height of the blocks, the variations of length being only in the lower plane of operation whereprovision is made for the same in the means for adjusting the loweradhesive and pressure mechanisms.

For any given length of box, the maximum distance between pressure heads7 and 8 will be the length of the box, plus the extent of verticalmovement of the form-.

ing block 4, the minimum distance being the length of the box with theends compressed between heads 7 and 8 and the opposite ends of theforming block. Thus it will be seen that the first action of pressurehead 7 on the forming block will be to force the block downward againstthe resistance of spring 38 to the limit of the vertical movement of theblocks when the folded end portions of the box having the adhesivethereon will be firmly pressed together to form the joints, the amountof pressure applied in the operation being determined by the adjustmentof screw 91.

As the forming block carrying the completed boxes thereon move from theD to the A position, the cam follower 42 is brought into engagement withcam 43 and the ejector arms 47 48 are actuated to kick the box off theforming block which will then be ready to receive another box blank asit comes to a stop in the A position.

It will be observed that the box supporting units 4 move in a plane andthrough a cycle of operation common to all the units, there being fivesuccessive steps of operation in the cycle, i. e., placing of the boxblanks on the forming blocks, folding of the parts to be glued to formthe joints, applying the adhesive to the folded parts, forming thejoints under pressure and removing the fin ished product from theforming blocks upon completion of the cycle.

From the foregoing detailed description and the illustrations of thedrawings, the construction and operation of the improved box makingmachine will be readily understood, and its outstanding advantagesappreciated by those experienced in the paper box industry. It will beseen that the machine is of simple, substantial construction that it canbe produced and furnished to the trade at relatively low cost, that itis adapted for operation by ordinary, or unskilled help, that it isadapted for relatively large output, that the product may be varied insize and shape as required, that the machine, as here shown, is adaptedin large part, and can readily be adapted for automatic operation, thatthe successive steps of folding, applying the adhesive, and forming thejoints are performed simultaneously on the opposite ends of the box,that the machine in all its functions of operation is adapted to producea high quality product at relatively low cost, and that the machine iswell suited to the requirements of users whose requirements or tradepolicies make it undesirable to carry a large stock or ready made boxes,who thus are enabled by installing box making machines of this characterin their own establishments to make their own boxes as needed at lowercost and with a much smaller stock of material.
